Aphids are small (less than 1/4 inch long), soft-bodied insects that suck sap from leaves, twigs, or roots. Depending on the species and the plants they feed on, they may appear:
They are pear-shaped insects with long legs and antennae. Adult aphids can be winged or wingless. They are often clustered on new growth.
Habits & Reproduction
Although aphids are most common in spring and summer, some species mate and produce eggs in fall or winter, which provides them a more hardy stage to survive harsh weather. Under ideal temperatures, many aphid species can complete their life cycle in less than 2 weeks, and because of their prolific reproductive capacity, enormous populations of aphids can build up in a short time.
